Problems solved by technology

[0005] However, it is difficult for the above-mentioned jacking device to ensure that the installation positions of the cylinders on the left and right sides are consistent, and when the cylinders are fed with gas, the movement of the cylinders on the left and right sides is difficult to synchronize. Steady, resulting in non-parallel contact between the lifting platform and the top plate, resulting in a gap, which in turn leads to the failure of the circuit board test on the automatic test machine

Embodiment Construction

[0020] Below, the present invention will be described in detail with reference to the accompanying drawings.

[0021] Such as Figure 1-3 As shown, the present embodiment provides a single-cylinder jacking device, including: a jacking base plate 6, a lifting platform 5, a support plate 2 arranged on the jacking base plate 6 on the left and right sides opposite to each other, and a support plate arranged in parallel with the support plate 2. A chute plate 1 with a chute, a connecting rod 15 fixedly connected to the two chute plates 1, and a single cylinder 10 arranged at the bottom of the jacking base plate 6. The slide rail, the chute plate 1 and the support plate 2 are connected through the bearing 14 arranged in the chute and the slide rail, the bearing 14 is connected with the lifting platform 5 through a shaft (not marked in the figure), and the connecting rod 15 is connected with the cylinder 10 When the movable end of the cylinder 10 is stretched out, the connecting rod...

Abstract

The invention provides a single-cylinder jacking device. The single-cylinder jacking device comprises a jacking bottom plate, a lifting platform, supporting plates, sliding chute plates, a connecting rod and a single cylinder which is arranged in the bottom of the jacking bottom plate. A slide rail parallel to the jacking bottom plate is arranged on each of the supporting plates, the sliding chute plates are connected to the supporting plates through bearings in the sliding chutes and the slide rails, the bearings are connected to the lifting platform through shafts, and the connecting rod is connected to a movable end of the air cylinder. According to the single-cylinder jacking device provided by the invention, in a way that the single cylinder is arranged on the jacking bottom plate and the sliding chute plates are driven by the connecting rod so as to drive the lifting platform to raise and fall through movement of the bearings in the sliding chutes and the slide rails, the disadvantages that double cylinders are hard to synchronize in mounting position and movement, so that the single-cylinder jacking device is simple in structure and convenient to maintain, and the lifting stability and reliability of the lifting platform are improved.

Description

technical field [0001] The invention relates to the technical field of jacking equipment, in particular to a single-cylinder jacking device. Background technique [0002] In order to control the processing cost and quality of the product, it is necessary to strictly control the one-time pass rate and processing waste in the production process of the product, and the precision requirements for the automation equipment and its mechanism are getting higher and higher. [0003] For the jacking device applied on the automatic circuit board testing machine, its jacking stability, parallelism and reliability when in place are indicators to measure the precision of the jacking device. [0004] The existing jacking device uses double cylinders as the jacking power, and uses four guide pillars as the guide in the vertical direction. The jacking device includes: two chutes arranged on the left and right, two cylinders for pushing the chutes to move horizontally, and a lifting platform...
